"Little Pony! Little Pony!! There's a letter from home, and you've been sealed! Yue Yang waved the letter and ran over, Lu Yun followed behind, holding two light bulbs in his hands, and he was also happy.

"Great creation? Still in this position? Ma Qiang looked at the letter in his hand and looked suspicious, shouldn't this position be from the Qin Dynasty.

"It is true that there is still this position, but it is an unsealed void lord, only Suilu, which is eight hundred stones." Xian Yufu explained and said, "Sir, this is the sixteenth lord, and when you want to wait for Mr. to stand up, you will definitely be able to be crowned a marquis." ”

Eight hundred stones? How much is that? It's not as expensive as the soju he sent out, so Liu Hong is stingy.

Ma Qiang stuffed the letter in his hand, picked up the newly sent light bulb, and said to Lu Yun and Yue Yang on the side: "Yang Chi, they have completed the question I gave them, how is your hydraulic hammer doing?" ”

Yue Yang scratched his head and muttered, "Someone must have helped, otherwise with Yang Chi's brain, how could he have thought of such a solution." ”

"Don't you have your father's help? It's just a hydraulic hammer, I not only told you the principle, but also took you to make a hydraulic mill, there is no difference between these two things, just let you improve the frequency, what's so difficult, go quickly, don't pestle here. Admiral Ma Qiang kicked Yue Yang away, and then let Lu Yun, who was giggling non-stop, follow, this guy in the province will sleep after a while, and he can send anyone to send a letter, this kid just wants to be lazy when he comes in person.

The hydraulic hammer is actually the improvement of the water cone, but the frequency and weight of the lower blow are higher, a good hydraulic hammer can reach one or two downward strike speed per second, which can effectively reduce the labor cost of forging.

But such a hydraulic hammer can only be roughly processed, and the so-called idea of building plate armor with a hydraulic hammer is almost impossible, and the plate armor needs to be close, and the hydraulic hammer cannot achieve such accuracy.

"Orange, Lime, how's your two homework?" After Ma Qiang took a bath, he paced to a wooden house while fanning the wind with a newly made folding fan, in the wooden house, the originally youthful Lu Qingcheng and Lu Qinglime's hair was about to drip oil at this time, and the two of them took a few people in the two test areas, Lu Qinglime was full of various test tubes and alcohol lamps and other things, and even a pot that looked similar to a pressure cooker, and Lu Qinglime's side was full of large and small buns and copper wires and light bulbs for testing.

To be precise, these are pre-produced dry batteries.

This is a zinc-manganese dry battery, the positive electrode is a carbon rod, the negative electrode is a zinc sheet, and the middle is mainly manganese dioxide, adding a mixture of ammonium chloride.

Manganese ore has been found, and zinc is purchased lead ore, and lead and zinc are associated and are found everywhere in the country.

Ammonium chloride is another compound produced by Hou's alkali production process in addition to soda ash, but ammonia is required.

Ammonia Ma Qiang is synthesized with nitrogen and hydrogen, this synthesis requires the use of iron catalyst as a catalyst, and requires high temperature and high pressure, and hydrogen can be electrolyzed, but nitrogen can only be obtained by removing oxygen from the air, so it can only be made in the laboratory for the time being.

It is Ma Qiang's ambition to cultivate a scientific research team as soon as possible, so that he can concentrate on some high-tech research...

Have you ever seen a big boss in a lab who personally washed the test tubes?

"I've made hundreds, huh!! How many more times are we going to try..."Lu Qingcheng felt like he was going crazy.

Although the principle is known, how to match each material still needs to be constantly tried, such a boring work, of course, let the beautiful girl do it, Ma Qiang himself is too lazy to do it.

"Okay, relax, let's go, let's go see the waterwheel and the water mill." Ma Qiang waved his fan and allowed them to let off steam.

"Yay! It's finally time to get out! Lu Qingcheng threw away his things and ran out of the house immediately, while Lu Qingcheng took someone to clean up before coming out.

Looking at Lu Qingcheng's appearance, Ma Qiang sighed, it seems that it is impossible to realize the dream of cultivating a beautiful girl scientist.

A sexy female scientist in a white coat for scientific research, studying physics during the day and biology at night, this was Ma Qiang's dream in the scientific research institute back then....

It's a pity that there seem to be more such scientists only in the island country next door...

"I made it! I did it!! Ma Qiang, who was observing the operation of the gears, suddenly heard a wolf crying and howling in the distance, and then saw Yue Yang running over with tears of excitement and relief in his eyes.

"One breath twice! One breath twice! I finally did it! With that, Yue Yang excitedly began to dance, almost turning his head.

"Okay, calm down, everyone knows you're fast, it's okay, man, it's not your fault that you're fast." Ma Qiang casually dealt with the following, and then asked Lu Yun who was following behind, "What is the data of the hydraulic hammer?" How many hammer attempts have you already attempted? ”

"We changed the gears again, and accelerated the speed of hammering, and the waterwheel can be hammered five times every time it turns, about one breath, and my uncle said that it should have four or five hundred catties of strength."

Should, probably... Yes!!! This data report will be torn up by itself in the future generations.

And what kind of breath, a stick of incense, what is this, can it be reliable!

Damn empirical judgment, there is no accurate value in everything, Ma Qiang remembered that when he used to live alone, he learned to cook, and looked at the scene where the so-called small amount, a little, and appropriate ingredients were all over the screen.

Forget it, you have to get used to it...

I'll be fine when I make my own pocket watch.

This hydraulic hammer should be usable, and in this way, his task in Yangshugou is basically completed.

It's time to go back.

Lin Zhi also quarreled several times and wanted to go back to see Lin Huan, hey, it's really difficult for children to bring.

That night, Ma Qiang said his idea of preparing to take people back to the Red Star Camp, and Lu Qingcheng learned that he finally didn't have to make dry batteries anymore, so he hugged Lu Qinglime and cried.

Ma Qiang shook his head, looking at this Nizi sad, thinking that he didn't finish his homework well back then, and he was also so sad, hey, go back and make up for her class.

Ma Qiang left Yueyang's team behind, while Yue Liang followed him back to preside over the construction of the steel plant.

When passing by the road repair site, Ma Qiang specially checked the mountain road built, although there is no various machinery in later generations, but the speed of the road repair team is not slow at all, nearly 60 miles of mountain roads have been repaired for more than 30 miles, and the cement has also been paved for more than 10 miles, thinking that it will be connected to the outside of the mountain in another month.

Ma Qiang calculated the time, it was already September, and when the road was repaired, it should be October, and the ordnance should be ready by the end of the year, and it was still too late.

Sitting in the carriage, Ma Qiang began to calculate the strength of his side in the event of a war.

Ma Qiang knows that he can't fight, and the various strategy games he has played in his spare time are his only military experience, but even in that kind of strategy game, he can only play the standard difficulty, and he has to kneel when he encounters coldness, so he will definitely not be so arrogant that he thinks that he can become a famous general if he crosses over.

Let professional people do professional things, this is what leaders should do.

Now there are two brothers Xian Yu and Yan Rou who can lead troops in the camp, among which Yan Rou can be regarded as a general of the main army in history, but there are no strategists, no famous generals to lead the team, and I am always not at ease.

It's time to get some help.
